Talk:Relativistic similarity parameter

Is expression for normalized vector potential correct? In the page, it is $${a_0=eA/m_e c^2}$$, but it seems incorrect because $${e A}$$ have dimension of momentum but $$m_e c^2$$ have dimension of energy. I think this should be $${a_0=eA/m_e c}$$. Am I right? YoshiGosu (talk) 11:46, 31 May 2017 (UTC)
